Study of lubricant jet flow phenomena in spur gears: Out of mesh condition [PDF]

, 1983
The penetration depth onto the tooth flank of a jet of oil at different velocities pointed at the pitch line on the outgoing side of mesh was determined. The analysis determines the impingement depth for both the gear and the pinion.
